To all iii/wm. z'zL- may concern.'

Be it known that we, JOSEPH N. MCFATE and HERBERT L. GLAZE, both citizens of the United States, residing, respectively,A at Phoenix, in the count] of Maricopa and lLos Angeles, in the County of Los Angeles and State OtCaliiornia, have invented new and useful Im' provements in Tires, of which the following is a specilieation.

This invention relates to tires, and more ly to tires in which solid compres` sible cushion members are employed within the casing, in contradistinction from a Huid vushion el nient, such" as an air cushion, and it has` for its object to provide'an improved tire oi this character which will be superior in point or" relative inexpensiveness and simplirity, talien in conjunction with increased durabilitv, length of life, facility in assembling, disconnecting and replacing of parts,

Vfreedom from liability`to get out of order or failure in service, and'ca-pable of being positively maintained in working condition or condition for service, and which may be conveniently and effectively assembled and put into condition for service, and which will in all general respects be superior in elilciency and serviceability.

lilith the above and other objects in view, the invention consists in the novel and usei'ul provision, formation, construction, combination and association of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in claims.

Fig. 5 is an isometric view of a wedge or spacer element in detached position, nuinber of such wedge or spacer elements being lindicated in Fig. i, and the saine being provided in installation in alternation with the cushionfmeinbers surh as shown in Fig. Ll.

orresponding parts in all the figures are designated by the saine reference characters.

eferring with particularity to the drawing, C designates the telly and 6 designates the rim oi a vehicle wheel, to which is shown applied a tire constructed in accordance with the invention and including or comprising an outer casing l) and a plurality et cnshimi members E whirh are disposed casing D'and the rim G. rlhc casing l) is held to the rim and thereby to the telly in the usual or any preferred manner, and with the rim entirely incloses a cushion Space, indicated in pait at c, and within which disposed the elements, namely, the cushion members .F .vhereby resilience and spring quality is gr. en to the tire.

the cushion members E, and which wedge or spacci' elements, together v-.fith the rushion members E, comprise ay continuous series et parts extending in annular formation around the rim 6. i

H designates means for binding toget the cushion members E and the spacer nu. bers F in working yrelation and iiimly h ing the same upon the rim G. G designates means for adjusting and tightening t ie means H and holding said means ll in operative condition to bind the members E and F to the rim G, as stated.

Each of the cushien members E, as particularly shown in Fig. fl, comprises a central body portion llfhaving substanti: opposite parallel bearing faces lying planes extending circnni'fei'entally oi' the wheel. The body portion ll in each instance developed into an enlarged crown or head lla, which lies in the same plane as the lbody ll, and the upper or outer sur- Lface of which is curved both circumferentially of the wheel and transversely oi the wheel, as at 11b to lit and contorni to the curvature of the inner wall or" the casing D. Curved abutments il project Vtroni the opposite parallel faces of the body ll, in the Ll O abutments 11, however, Vis abruptly iii-- .tie inner termina creased in pitch toward as at 11d, whereportions oi' such abutments,

Y

Alternating with the cushion members Fi are the wedge or spacer members F wiiich comprise each a central body portion' S which Imay 'be cored out or chambered, as at 8d, for Y lightness,V without surrender of strength, and from which body S project at each end spaced prongsSb. The outer sides` of the body and of the prongs may be roughened or serrated as at S@ to lirinly engage thev .saine 'lrictionally with the iiinerwall ot die casing, and are slanted inwardly 'for wedge action attlie bottom of the inner walls of the casing. Eachv of the members F will readily be stamped or struck out otmetallic blanks, or, if preferred, may be cast, or may be molded or otherwise Yformed ot any suitable material. Y

. The prongs 8l are so spaced apart at each end of the member F as to engage one of the abutments 11c of the next adjacent cushion member E; and as indicated clearly in Fig. 1 and in Fig. 3, these spacer elements are introduced between adjacent cushion elements E, with each pair of prongs 8b engaging one ot the adjacent abutments 11, and such spacer elements are wedged lirmly down into the space between adjacent cushionk elements, so as to iirmly position the same within the easing D.

Registering openings 5 and 6a. are pro- Vvided in a series throughout the assemblage of cushion -members E and spacer members F, the openings 5 beingin themenibers E, the openings 6 in the other mentioned members; and through such series of registering openings is passed a length 9 of suiting Ymember for cinching vand `sp acer member ,tene'd'sides forming a square A. screw cap 15 f wrench,

and spacer yendsV of the binding wire A' drawing,

said -in the usual manner. ln so assembling suoli able wire7 cable or other material oit high tensile strength, the saineA serving as a bind i the elements E and F down-upon the rim 6, in complete assemblage. VThe endsoic this cableoi mi- 7o k.lar length 9, are brought together and atltaclied to the outer end of a tighteniiig pin 12 which is rotatably mounted in corresponding radial bores in the 'telly C, rim 6, 7 This spacer member '7 is constructed the same and operates the same as the spa-cer members F, and en vcept that it is devoid of the binding wire .holes y6a, and is further provided with thickened body 8,'befing bored, as stated, to So receive the .pin 12 rotatably. VThis pin 12 llikewise extends inwardly ot vthe Alolly,

passing through a. perforated plate :ip-

pliedA .to the telly between two ot the spokes v'a flat-sided opening 13a adapted to receive a correspondingly vformed locking ring 13b which is sil 1lably mounted'aipon the threaded inner project- Aing end .12L ofthe pin 12, and which pin is ilattened at opposite sides as at'12" jtliroup'li- 9o out the Ythreaded portion and to the er; inner end thereof; The vestreme inner end of'tlievpin 12 is devoid of threads, its flatfor Ireceiving a wrench or other device for turning the pin. y is applied to the pin 12, at its .threaded portion 12, holding the locking ring 13b in the `flat-sided opening 13L in the plate 13, ,to prevent rotation oit' the pin 12 atter it has vbeen su'fliciently rotated by a 100 as described7 to give the binding. wire 9 one or morey .turns about the inner end ,of the pin, orvlthe reduced portion thereof, as at 12C, to put the cushion members members under pressure and '1G75 against the rim (5. The 9 are passed through a cut or lrert 12b, in the outer ond ot' thev pin 12', and are bound therein by a screwv'tlireaded 'through such slotted porhol d the same firmly iio tion of the outer-end of the pin, such screw being shown at 12e.

The operation, method 'of use, and advantages of the :improved tire feonstruitcu. :and the `improved features thereof, entering into and comprised withinv the invention.

and embodying the sameI will be readilyT understood 'from the roregoing description,

taken in connection with the accompanying and the following statement The members'llaud are assembled getlier in alternation in thecasing D, and casing is Y'then installedupon Vthe rim. (l

LAQ ot the binding wire 9 are firmly secured to 130 held by tightening down V'elements E and F the eXtreme inner end of such pin and so the binding' screw 12e. In placing' the casing' L`nd its contained Y andbinc ig' wire 9 and pin 12, upon the rim,'suchpin l2 is passed through the registeringy openings in the telly and rim, in the same manneras the air tube with its valve is put in place in applying' a pneumatic tire to the rim and 'tel i et the wheel. This brings the inner end or" the pin 12 through the plate 'i3 and its opening' i3, in position for manipulation by a wrench or to receive the cap l5 to hold the locking; ring' lei in place, after the cinching' down and tightening` of the members E and F by the binding wire 9. The cushion members or elements E, the square ends of the crowns or heads 11'L all orn which abut against each other ina continuous series ot such heads extending' throughout the tire, are the active elements of the tire from the standpoint of `resilience and spring'quality, and such elements are preferably formed of rubber, rubber substitute, or any suitable material having sufficient resilience and spring quality, together with su'fiicient stability to perform their function of supporting' the load which is imposed upon the wheel. lt will be seen that these members E are permitted a material degree of compression, which is accommodated by the open spaces, indicated at 8, over which arch the abutting ends of the heads or crowns lla, and within which open spaces the spacer or wedge elements F are installed. Likewise, this compression is accommodated by the materially open space, as at e, at each side ol each clement l1, and adjacent to the abruptly curved portions il of the abutments llc. Thus the expanding' and contracting of such elements, in the rcsilient play'of the same responsive to imparting` of the load to the roadway through the casing'. in the rotation of the wheel, are provided forand accommodated within the casing D, and without ldistortion of the casing or variation of its evenly curved surface presented to the roadway.

rlhe spacer elements l1l maintain thc cushion elements E, in proper fixed relation each to the others, in a working' series around the rim, circumferentially, andthe binding wire 9 suitably tightened by the ti,0,hteninn means G maintains the entire L lassemblasre el elements .E and F 1n proper working relation and positioned upon the rim 6 and within yielding' arched tread organization, firmly held in place and to the rim, within the easing', and by which the tire is given a resilient orV spring' quality accompanied by an c?- hcient load-sustaining quality; and wl' hv organization may readily and conveniently be assembled together, and also disassembled or dismantled to introduce, 'i required, 'fresh elements, or repair or replace any broken or damaged part which under any circumstance might require such treatment. It will be noted that the wedge or spacer elements l" are slightly beveled or inwarfilly inclined at their side edges, thus tending` to wedge the casing D at its side walls between the flanges on the rim 6 so as to firmly hold the tire parte in assemblage upon the rim.

The present tire provides full andl suieient resilience with its other features of advantage, and at the same time is puncture proof, thus overcoming` the principal objeo tion to the pneumatic tire.

t is manifest that many changes and variations may be made in the constructimi and iliormation and inter-relation and mode of application of parts, members and ifeatures, in distinction from the disclosurry i the foregoing' description and statement and drawing, in adapting the invention to vei'ving conditions or" se or service or to Varying preference, without departing ir the true spirit or" the invention.

Having thus disclosed our invention claim and desire to secure by Let a tire, a series ot similar and inter able cushion members adapted to be between the easing' and the rim and provided at their outer en o" the casing, spacer elements interposed between the faces oi the cushion members, and means for binding' such cushion members and spacer elements down upon the rim oit' 'the wheel ina continuous series.
